The present invention relates to a coupling assembly having a coupling and a nipple for coupling hydraulic hose, and more particularly, to a coupling assembly for quick connection and disconnect of the hydraulic hose located between a hydraulic source and a hydraulic tool by providing improved internal and external structures and a coupling structure to a coupling mounted at an end of a hydraulic hose in order for joining the coupling with the nipple firmly, thereby enhancing watertightness by preventing the fluid inside the hydraulic hose from being leaked to the outside regardless of pressure intensity and making a smooth flow of the fluid. The coupling assembly for coupling hydraulic hose according to the present invention comprises: a main body; an insertion body inserted into the inside of the main body and connected with a nipple; a valve inserted into the insertion body to control the flow of a fluid; a sealing inserted into the insertion body to surround the valve; a sealing presser inserted into the insertion body to press the sealing; and a locking sleeve mounted on the outer circumferential surface of the insertion body to strengthen a connection between the coupling and the nipple. |
